Tattoo Particles: Picosecond Laser Versus Nanosecond Laser

May 27, 2024 updated by: Lynhda Nguyen, Universitätsklinikum Hamburg-Eppendorf

In Vivo Analysis of Tattoo Particles After Picosecond Laser Compared to Nanosecond Laser

- For treating unwanted tattoos, the gold standard treatment is a nanosecond or picosecond laser. However, comparative microscopic analysis is limited. Therefore, the aim of the present study is to analysis morphological changes of tattoo particles and surrounding tissue in human skin.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Nanosecond laser
Patients with unwanted tattoos who plan a nanosecond laser treatment will be recruited for measurements using a multiphoton-tomography system.
Other: nanosecond laser treatment + measurement with a multiphoton tomography system
Patients with unwanted tattoos who plan a laser treatment will be recruited for measurements using a multiphoton-tomography system. These are scheduled 6 weeks and 12 weeks post-treatment.
Picosecond laser
Patients with unwanted tattoos who plan a picosecond laser treatment will be recruited for measurements using a multiphoton-tomography system.
Other: picosecond laser treatment + measurement with a multiphoton tomography system
Patients with unwanted tattoos who plan a laser treatment will be recruited for measurements using a multiphoton-tomography system. These are scheduled 6 weeks and 12 weeks post-treatment.
